Abstract
A hollow fiberglass bulkhead is constructed for submersion in a swimming pool. Two boxes open-top and open-ended are joined, a shelf is added, end supporting hardware is added, a bottom is placed on the box and the ends are closed and the box is then inverted to be installed in the swimming pool. Balsa wood plates provide rigidity and partial flotation while two end rollers prevent the bulkhead from becoming twisted as it is moved along the pool.

A movable, submersible bulkhead for a swimming pool, comprising:
- an elongated hollow body having top, bottom, end and side walls formed of fiberglass and resin, and a platform between the top and bottom walls and joining the side walls, openings in said end walls for providing ingress of water into the body, slots in the side walls at the water level for dampening wave action of the water, said side walls of said body including cores of balsa wood for rigidifying the body and providing partial flotation, and means for supporting and aligning the body within the pool including a pair of transversely spaced rollers on each end of the body for engaging the pool for carrying the weight of the body and preventing rotation of said body when the same is moved laterally along the pool.
